Reaction Steps

Acetone (1.0 mL) and tert-butoxy potassium (2.7 g) were added to a solution of 3-nitroaniline (1.38 g) in dimethylsulfoxide (20 ml), and the reaction solution was stirred at room temperature for 3 hours. The reaction solution was diluted with ethyl acetate, and washed successively with an aqueous ammonium chloride solution and a saturated saline solution. After drying over anhydrous sodium sulfate, the solvent was evaporated under vacuum. The residue was purified by column chromatography on silica gel (developing solvent:hexane-ethyl acetate) to obtain 2-methyl-4-nitro-1H-indole.
